Elderly cat

Question
Hi, I have an elderly female cat. She is 16 yrs. old and she is on thyroid medication. She is very thin and is an indoor cat. She hasn't had any shots for a few years because of her age and has been eating the same food for years. She doesn't seem to drink excessively and her stools look normal. The problem is last night she had mucus and clear liquid coming from her rectum. Do you have any suggestions? Because of her age we are unsure about getting too many tests done on her. Thank you.

Answer
You might want to have her thyroid levels checked as the medication can cause some side effects if she is getting to large a dose. A little blood pull is all the vet should have to do.

Mucousy stool can be caused by food intolerance also but since she hasn't had any issues with that up till now I would suspect the medication first. If not, it could be that because of her advanced age she might not be tolerating the same food as well.

This is something you should discuss with your vet but I would definitely have a medication check first.

Vaccinations are not something I would worry about at this point.
